seems to be an isolated case. need more system information. can you run https://github.com/RustAudio/cpal/blob/master/examples/beep.rs ?

[abitrolly]

@chaosprint no. how to run it?

[chaosprint]

@chaosprint no. how to run it?

1. install rust https://www.rust-lang.org/tools/install
2. git clone https://github.com/RustAudio/cpal.git
3. cd cpal then cargo run --example beep

[abitrolly]

@chaosprint using brew own rust, it beeps okay.

$ cargo run --example beep

I suspect there are some problems with dependencies. At least I don't see the /home/linuxbrew/.linuxbrew/Cellar/alsa-lib/1.2.12/lib/alsa-lib/libasound_module_pcm_pipewire.so the it is trying to find.

Maybe it is possible to use pipewire API directly?
